What is the volume of the following prism?

ira [324]

Answer: $\Large\boxed{B.~\displaystyle 75~m^3}$

Step-by-step explanation:

Given information

Height = 2 m

Base = 5 m

Length = 15 m

Given the formula for Triangular Prism Volume

$V~=~\displaystyle \frac{1}{2}\times ~b~\times~h~\times~l$

$\to V=Volume\\\to b=base\\\to h = height\\\to l = length$

Substitute values into the formula

$V~=~\displaystyle \frac{1}{2}\times ~(5)~\times~(2)~\times~(15)$

Simplify by multiplication

$V~=~\displaystyle \frac{5}{2}~\times ~30$

$\Large\boxed{V~=~\displaystyle 75~m^3}$

Hope this helps!! :)

Reduce 7y + 2y 2 - 7 by 3 - 4y.

NARA [144]

Answer:

D. $2y^2+11y-10$ .

Step-by-step explanation:

Given:

We need to reduce $7y+2y^2-7$ by $3-4y$

Solution:

To reduce the equation means we need to subtract the one equation from other.

First we will arrange the equation n proper format we get;

$2y^2+7y-7$ ⇒ equation 1

Also Arranging other equation we get;

$-4y+3$ ⇒ equation 2

Now we will subtract equation 2 from equation 1 we get;

$(2y^2+7y-7)-(-4y+3)$

Now Applying distributive property for the sign we get;

$2y^2+7y-7+4y-3$

Now Arranging the like terms we get;

$2y2+7y-+4y-7-3\\\\2y^2+11y-10$

Hence the reduce form of the given equation is $2y^2+11y-10$ .

You just won a contest! you will receive $100,000 a year for 20 years, starting today. if you can earn 12 percent on your invest

ladessa [460]

The formula that we will use is:
C × {{1 - [1/(1 + r)t]}/r} +c

C = 100,0000
r = .12
t = 20

= 100000 * {{1 - [ 1/ (1 + .12)^19]}/ .12} + 100000
approximately 836,577.69

I am using a scientific calculator so just insert right the number and you will come up with the correct answer. The answer in this question is $836,577.69

Find the area of an equilateral triangle if a side is 8*sqrt(3) m. Round to the nearest whole number.

gavmur [86]

Hello,

8*√3 is the side.
The height is √((8√3)²-(4√3)²)=√(64*3-16*3)=12

Area of the triangle=8*√3*12/2=48√3≈83
